On ABC's Once Upon a Time in Wonderland, some secrets about the Red Queen and her past as Anastasia have already been revealed. BuddyTV got the chance to speak exclusively with Emma Rigby about this week's big episode and how fans might feel about the Queen once they know more about her past.

Not all titles featured on BuddyTV are available through Amazon Prime.

What can you tease about this week's episode, "Heart of Stone"?

Emma Rigby: This is actually my favorite episode. I had the most fun filming this because I got to play two different characters back-to-back. We see Anastasia and Will together and then suddenly it's intermixed with the Red Queen in all her full glory ruling Wonderland. What the audience will discover is who Anastasia was and the events that led her to how she became the way she is now. It was really exciting to play and [there are] a few twists, and obviously there's a big reveal that I think people will be quite surprised about.

The Red Queen started out as pure evil, but we've already seen hints to her softer side. How do you think this episode will affect the way fans see her?

Emma Rigby: I think they're going to be exposed to both sides. I think they're really going to love her and really hate her. For me, that's the best part, that every character - you know, in real life everybody has [different] sides to them. Nobody is perfect and that's kind of what is explored - people's reaction to the situation they are put in. I think the audience is really going to have that love/hate relationship.

Did you have a similar reaction to the Queen as you read the scripts? Did you know from the beginning that there was more to her story?

Emma Rigby: No, I had no idea. When the creators met me, I was reading for Alice. Then they met with me and they were like, "Actually you would be brilliant as the villain, the Red Queen."

I knew that the writers knew that there was another side of me. So I sensed that we were going to somehow see who the Red Queen was. I've got really young qualities and I look young as well so we can do these [scenes] before where we see Anastasia as this little girl with the Knave. For me that's great.

We're shooting [Episode] 10 at the moment, and [Episode] 5 is a big moment for me, but 10 is as well. So it's great that that kept going throughout the series.

How much more are we going to learn about the Red Queen in future episodes? Are there even more huge revelations coming?

Emma Rigby: I'd say that Episode 5 and 10 are kind of a concentrated reveal, but I think it will be great for the audience to see [Episode] 5 because then they'll understand the journey that the Red Queen goes on through [Episode] 5 to 10. It gives a little bit more understanding for the audience and certain things will make sense, which I think the creators and writers do brilliantly. It really allows the audience to study a character and be like, "Oh, okay, I understand that now." And then suddenly when they least expect it, "Wow, I did not see that coming."

I read [Episode] 10 and I was really excited. There's new things coming along into Wonderland all the time. There's a lot happening as the series goes on and I feel like every episode gets better.

It's also important for us to differentiate ourselves from [Once Upon a Time]. A lot of people I spoke to [in the beginning] were like, "Oh, yeah, I've seen that before." And I was like "Oh no, it's actually a very different show."

We wanted to show people who don't watch the other show, can they can still enjoy our show, because it's not really connected. It's its own drama. We want people to be able to enjoy this show as a stand-alone show.

Do you think the Red Queen could ever revert back to being the girl who was in love with Will or is that past too far gone now?

Emma Rigby: I think the plan is that our show is a self-contained story so it will have an end point with this particular story. I feel like that's what the writers want to achieve with our show.

I think what's brilliant about this show is that anything is possible. We are in a fantasy world. With the Red Queen there is always hope. Who knows what she's capable of and what is possible? So I think that's the exciting part, the audience is left wanting to know what is next because there's no rules in Wonderland.
